FUEL-OIL BURNER.

oreoo.

To all whom. it may concern:

lie it known that T, lVILLL-wr R. Cocurhm, J13, a citizen of the United Stat and resident of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful improvements in Fuel-Oil Burners; fand I do hereby declare the following to-he a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertai'ns to make and use the same.

My iov'cniion relates to an improvement in fuel oil borders, the object bein to provide a n oil burner that will be simple, economical and be easily and readily applied within the the pot of any ordinary coal or wood burning; stove, and it consists in the parts and combination of parts as will be more fully described and pointed out in the claims;

in the accompanying drawings, Figure 1 a View in erspcetive of my improved device; Fig. 2 IS a View in lougitudinztl sec,- tiou tl'n-ongh the fire pot of stove and through the hollow frame of the burner;

" is a View in transverse vertical secon the line a, a: of Fig, 2, and Fig. 4 is view on the line ty---y resents a supporting frame of such site as to be readily entered in the fire ot l of an ordinary eozll or wood burning store; This frame is hollow and is preferably made of cast metal, rectangularin shape, closed at one end and open at the other end, and isproifided in its top with a flanged opening or openings 2 :l'or the pussage upwardly of air to the burner orifices. The portions of the top of the frame at opposite sides or -the openings 2, are inclined upwardly toward said openings, and the latter are located at the top of the incline 3, the; nndersiol'e' of the latter surfaces forming deflectors which deflect the air to the exit openings 2. This frame 1 is divided longitudinally by a centrally located horizontal partiti'l'm 1" extending from a point ad arflntthe front open end of the frame to a point in rear of the front air exit 2, and then p ojects upwardly to the top late of the frame, formin a flue thirou i whi h air to the trout an exit and both rjoripasses Specification of Letters Patent.

flees over same, while the portion of the frame below and to the rear of partition 1*, forms the supply fine 5 for the rear air open- 111 2.

The front open end of the frame 1 is adapted to pass through a door opening ht the end or side of the stove, as shown in Fig. 2, and said open end may project more or less aceordin to the size of the fire pot. This permits t: e burner to be so located within the fire pot, as to bring the burner orifices properly under the openings in the top of the stove.

lhogas generating and burnin structure comprises three connected one of which 7 is conneete with the Oil sup 'ly pipe 8. This pipe 8 is connected witl a source of oil supply preferably located so that the oil will be supplied to pipe 8 by gravity. Pipe 7 to WhlCll pipe 8 is connected, is located in a' vertical plane to one side of the burner orifices, but is within the heating zone of the latter, so that the oil passing tlicrethrough will be highly heated, and it is preferably filled with Wire strands extending lengthwise the pipe and loosely filling the same so that the coinparativcly small quantity of oil therein will he impeded in its progress thrmwh the pipe. This pipe 7 is connected by an clliow 18 with the vaporizing pipe 9, which is chnnected with the burner pipe 10. Pipe 10 is substantially parallel with the pipes 7 and 9, and is located immediately under pipe 9 so that the latter will be direotl exposed to the heatfrom the burner ori ces, The pipe 9 in which the heated oil' is vaporized, or in which any vapor anointed in i 6'7 is superheated, may also loosely fill; with wire which will impede the progress of any oil through the pipe and increase the heating surface to which the oil and vapor is subjected.

The burner pipe 10 is made of brass and is of smaller diameter than either pipe 7 0r 9 so that the )ressure of the vapor will be increased in t e burner, and it is provided with a burner orifice 11 for each air opening in the frame I. These burner orifices are nice minute, and are located centrally over ara lel pipes,

t e air openings 2 in the frame 1, so that the air passing up' and around the burner pipe will be about evenly divided at the two sides of the latter.

"With burner pipesmade of iron or steel,

the intense heat corrodes the pipe and causes it to scale. By making it of brass all corroding and-scaling is avoided and consequently .there is'no clogging ofthe burner openings due to such corroding and scaling.

The frame 1 is provided on its toptwo starting cups 12 and 13, which latter .aresiniply depresionsin'the top plate, and are adapted to receive oil, or asbestos pads soaked with oil, which when ignited, will heat the, pipes-79r and 10 sufficiently to start the-vaporization in pipes 9 and -10.-=

This, frameis also provided at its rear end. witha'n upwardly projecting integral flange 14:, provided on, its inner face with two vertical parallel ribs 15. and 16, separated sufii ciently to receive between them the closed free end 17*"- of the burner pipe ,10, and the rib 16 is provided with a hook shaped upper end 17, adapted to take under the elbow 18 and support and sustain-the rear ends of the pipes in proper position relative to-the air openings in the frame 1. The frame 1 is also provided in advance of the oil cup 12, with a flange 19 having a slot for the passage of theend of the-pipe s, so as toprevent any lateral displacement of the burner pipes atthe front. Tlhe pipe 10 preferablyrests in grooves 20 formed in the raisedpon,

tion of the top of the frame adjacent the air openings in the latter;

With this construction the.gas generating.

and burning structure as a unit,-can be lifted from frame 1, and-when seated on the latter,

will'be held securely against the of accidental displacement.

The open end 6 of the frame 1, is smaller than the door opening in the'stove a-ndto cover said opening I use a plate 21 having possibility I an opening therein of a size to receive said end 6, so that when said plate is'moved up against the outer side ofthe door opening in the stove it will close .the latter, to all air except that entering through. the frame. The end 6 of the frame is adapted to project through the door, so that it takes the air direct from the outside of the stove, consequently this'plate will be used only in instances where the end 6 does not substan tial-ly. fill the door opening. a

Inorder tofurther support the pipe sys teml-east the'post 22 integral with top of frame 1, about midway the burner orifices 11',- and in a'position to engage and form a seat for pipe 7 and I provide the said post 22, with a lateral extension 23, curved on its upper, face as shown in Fig. 3, concentric with 1 the curvature of pipe 9,, and but.

slightly removed from the latter. This curved extension 23 forms a support for the bar'25 commenting the two Spreaders the Spreaders with relation to the burner orifices, so as to permit the said Spreaders to be. so: placed centrallymwith relation to the flame.

' 2 Having fully described my invention what I claimas new and desire to secure by Letters-Patent, is ze- 1. The combination of a hollow frame closed at one end and open at the other end vand provided with a plurality of air openings and with a partition. forming flues, one flue leading to one air opening and the other flue to the other air opening, means integral with the top of the frame for supporting a gas generating and burning structure, and
